Touch means freedom! There is nothing as intuitive as a touch. Touchscreens provide a “language free” interaction between people and machines or apparatus and the smart phone and later on the tablet have had a great influence on that. More and more solutions are making the transformation from a one direction transmitter to a dual direction data transfer tool, for example wearables.

Especially our customers that service international markets can appreciate the simple interactivity of the combination of display and touch.

When mentioning touch, DISvue® focuses on 2 major technologies namely Resistive and Projected Capacitive.

Resistive is the technology where a transparent front foil is pressed down to the below carrier thus resulting in a lower resistance value on that spot. There are 2 types that are widely in use namely:

Resistive 4-wire – Mainly used in combination with lower cost and smaller size displays.

Resistive 5-wire – Mainly used in industrial applications (due to higher reliability) and larger type of screens.

Projected Capacitive touch(often abbreviated as PCAP or PCT) is offered in 2 versions, the standard size where sensor and carrier glass are identical (to a display) and the version with cover glass.

Below some highlights:

  • Touch controller may be integrated in the tail (COF type);
  • Durable and drift free;
  • High transparency;
  • Can be used behind a front glass;
  • Available in small and very large sizes (over 100 inch).

In most cases PCAP touch is still more expensive than standard R4W, also due to the touch controller integration. High demand is closing the gap between resistive and projected capacitive.
